Abstract

Markers of Alzheimer's disease (AD) are being widely sought with a number of studies suggesting blood measures of inflammatory proteins as putative biomarkers. Here we report findings from a panel of 27 cytokines and related proteins in over 350 subjects with AD, subjects with Mild Cognitive Impairment (MCI) and elderly normal controls where we also have measures of longitudinal change in cognition and baseline neuroimaging measures of atrophy. In this study, we identify five inflammatory proteins associated with evidence of atrophy on MR imaging data particularly in whole brain, ventricular and entorhinal cortex measures. In addition, we observed six analytes that showed significant change (over a period of one year) in people with fast cognitive decline compared to those with intermediate and slow decline. One of these (IL-10) was also associated with brain atrophy in AD. In conclusion, IL-10 was associated with both clinical and imaging evidence of severity of disease and might therefore have potential to act as biomarker of disease progression.

  • Pathways involving mitochondrial dysfunction or inflammation have been linked to rapid progression, but these associations may be downstream effects of true drivers of progression.

    “While pathways involving mitochondrial dysfunction or inflammation have been linked to rapid progression, these proteomic and physiological associations may be downstream effects of true drivers of progression [9–11].”

    From Genetic drivers of progression in Alzheimer’s disease are distinct from disease risk (2026) · cites this paper as [10]

    The Results section links changes in inflammatory proteins to fast cognitive decline in Alzheimer’s disease. The Discussion asks whether the peripheral inflammatory signature is secondary to inflammation in the brain, but does not establish that these associations are downstream effects of the drivers of progression. This paper does not address mitochondrial dysfunction. (LLM, conf=0.82)

  • Elevated CCL11 may contribute to driving neovascularisation in AMD via interaction with CCR3.

    “Elevated CCL11 in the plasma and cerebrospinal fluid seen in aging mice and humans are associated with declining neurogenesis, neurodegenerative disease, and cognitive decline and may contribute to driving neovascularisation in AMD via interaction with CCR3 [1, 93, 123].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
